REVERSING DEVICE FOR OVERHEAD ELECTRIC CARRIERS.

SPECIFICATION forming part of Letters Patent No. 692,118, dated'January28, 1902.

Application filed. April 19, 1961.

T0 aZZ whom it may concern.-

Be it known that I, AETHU S. CLIFT, a citizen of the United States, anda resident of East Orange, Essex county, State of New J ersey, haveinvented certain new and useful Improvements in Reversing Devices forOverhead Electric Carriers, of which the following is a specification.

Myinvention relates to appliances for overhead electric carriers orcars, and has for its object to provide a meansfor automaticallyreversing the motor at desired points-such, for instance, as at the endof a particular line.

In the drawings forming part of this specification, Figure 1 representsa motor equipped with a reversing switch and shows also the device foroperating the switch. Fig. 2 is an enlarged perspective view of theswitch.

A represents the motor, running on the cable 13.

C is a reversing switch of any desired con- Attached to the switch arethe arms D and E, by which the switch may be moved from one position tothe other.

F is a spring arranged to hold the switch in either position underordinary conditions of the movement of the carrier.

Secured to any suitable supports or in any suitable manner in the pathof travel of the arms D and E is a pivoted arm G. The construction, asclearly indicated in Fig. 1, is such that the arm will yield in onedirection only. The arms are placed at predetermined positions where itis desired to have the motor reversed.

The operation is asfollows: In Fig. 1 the car is supposed to betraveling in the direction of the arrow and to be about at the end [andhold it in position.

of its route, whereit-will be stopped by devices not necessary todescribe. As the car passes under the arm G the arm D on the switch willbe turned until the springF is on the other side of the center, as willbe clearly observed from the drawings. The spring F will then completethe reversing of the switch When the current is again sent through themotor, the car will move in the opposite direction, and the arm E, whichis now vertical, will pass under and lift the arm G, as indicated indotted lines, Fig. 1. At the opposite endof the line the arm D will bearranged in the opposite manner and will again reverse the switch.

What I claim, and desire to secure by Letters Patent, is

1. In a carrier for overhead electric railways the combination of themotor, a cylindrical reversing switch therefor and means forautomatically turning the switch at predetermined points, and a springtending normally to hold the switch in its extreme positions,substantially as described.

2. In a carrier for overhead electric rail- Ways, the combination of amotor, a cylindrical reversing switch, arms on said switch and means forengaging said arms at predetermined points to turn the switch, and aspring tending normally to hold the switch in its extreme positions,substantially as described.
